New Hydraulic Poppet Screw-in CARTRIDGE / SOLENOID VALVE # SV16-21, no name and no box but was in large Eaton box, most ar wrapped in plastic with red plastic cap inside,


DESCRIPTION
A solenoid-operated, 2-way, normally open, piloted poppet-type, screw-in hydraulic cartridge valve designed for low leakage in load-holding or blocking applications.

OPERATION
When de-energized, the SV16-21 allows flow from 2 to 1, while flow from 1 to 2 is severely restricted. When energized, the valve closes, blocking flow from 2 to 1. In this mode, flow from 1 to 2 will be allowed after overcoming the solenoid force. This requires 3.4 to 10.3 bar (50 to 150 psi).
Operation of Manual Override Option: To override, push and hold override button.

FEATURES
• Continuous-duty rated coil.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Industry-common cavity.
